Description

I would like to contribute a new example for embedded Timestamping.
The Timestamp is beeing embedded into the existing Signature (which has so be prepared big enough for it). So that the document does not get changed.
This Step is a preparation for the LTV and includes some reorganisation for Validation-Purposes.

exec:java -X -Dexec.mainClass="org.apache.pdfbox.examples.signature.validation.CreateEmbeddedValidation" -Dexec.args="${infile} -tsa ${tsa}"

CreateSignature has been changed to add SignatureOptions, where we can choose the size of the signature.
